Ask a specific question about this device

The Portable Oxygen Concentrator P2-TOC is intended to provide supplemental low flow oxygen.

The device is not intended for life support, nor does it provide any patient monitoring capabilities. This device is for adults only.

The Portable Oxygen Concentrator P2-TOC is a device that uses the principle of molecular sieve pressure swing adsorption to increase oxygen concentration by adsorption of nitrogen and other gas components. The device needs to be used with a nasal oxygen cannula, which can provide oxygen supplementation to the user.

The Portable Oxygen Concentrator P2-TOC has two oxygen supply modes, namely continuous oxygen supply mode and pulse oxygen supply mode. Hereinafter referred to as "continuous mode" and "pulse mode" .

In the continuous mode, the Portable Oxygen Concentrator P2-TOC can continuously deliver oxygen at a fixed flow rate. In the pulse mode, the Portable Oxygen Concentrator P2-TOC is able to deliver oxygen only when the user inhales by detecting the human respiratory rate.

The provided text describes a 510(k) premarket notification for a Portable Oxygen Concentrator (P2-TOC). It details the device's characteristics and compares it to predicate devices to demonstrate substantial equivalence. However, the document does not contain information related to an AI/ML-enabled device or a study involving human experts, ground truth establishment, or comparative effectiveness with AI assistance.

Therefore, I cannot fulfill most of the requested points as the provided document is for a physical medical device (portable oxygen concentrator) and not an AI/ML diagnostic or therapeutic device.

The document primarily focuses on:

• Device Description and Indications for Use: What the portable oxygen concentrator does.
• Principle of Operation: How it separates oxygen from air.
• Comparison with Predicate Devices: Demonstrating similarity in function and safety to already-marketed oxygen concentrators.

• Absence of Clinical Accuracy Testing: Explicitly states "There was no clinical testing performed." This is common for 510(k) submissions where substantial equivalence can be demonstrated through non-clinical means.

Here's what I can extract from the provided text regarding acceptance criteria and performance, focusing on what is relevant for a physical medical device:

The "acceptance criteria" for a physical device like a Portable Oxygen Concentrator are typically defined by compliance with recognized consensus standards and performance specifications. The "study that proves the device meets the acceptance criteria" refers to the non-clinical testing performed to show compliance with these standards and performance specifications.

1. Table of Acceptance Criteria and Reported Device Performance (Based on "Comparison with predicate device" and "Non-Clinical Tests Performed"):

Regarding the points specific to AI/ML devices, I must state that the document does not provide the requested information for the following reasons:

2. Sample size used for the test set and the data provenance: Not applicable. This document describes testing for a physical device's compliance with engineering standards, not an AI model trained on data. There is no concept of a "test set" from a data perspective. The "testing" refers to bench testing of the physical hardware and embedded software. Data provenance would not be a relevant concept as it pertains to clinical data for AI model training/testing.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. No clinical test set or ground truth established by experts is mentioned. The ground truth for device performance is based on physical measurements against established engineering and medical device standards.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable. No clinical test set requiring expert adjudication.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance: Not applicable. This is a physical oxygen concentrator, not an AI-assisted diagnostic or therapeutic device that would involve human readers.

6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done: Not applicable. This refers to a physical device, not a standalone AI algorithm. While it has embedded software, its "performance" is measured by its physical output (oxygen concentration, flow rate) and adherence to safety standards, not by an algorithm's classification or detection accuracy.

7. The type of ground truth used (expert concensus, pathology, outcomes data, etc): Not applicable. The "ground truth" for this device's performance is determined by direct measurement of physical parameters (e.g., oxygen purity, flow volume, noise levels) and compliance with specified engineering and safety standards, as detailed in the "Non-Clinical Tests Performed" section.

8. The sample size for the training set: Not applicable. This is for an AI/ML model, not a physical medical device. The device itself is manufactured; it doesn't "learn" from a training set in the AI sense.

9. How the ground truth for the training set was established: Not applicable. See point 8.

In summary, the provided document is a regulatory submission for a physical Portable Oxygen Concentrator, and therefore, the information requested, which pertains to AI/ML device performance and validation studies, is not present. The "acceptance criteria" and "study that proves the device meets the acceptance criteria" for this device are based on demonstrating compliance with a comprehensive set of recognized consensus engineering and safety standards through non-clinical bench testing.

The Oxygen Concentrator provide supplemental oxygen to patients who require supplemental O2, by separating nitrogen from room air, by way of a molecular sieve, it can be used in the home or health care facility. It is not intended to sustain or support life.

The Oxygen Concentrator is a portable concentrator which could utilize a molecular sieve and pressure swing adsorption to produce the oxygen. The device could separate nitrogen by absorbing through the molecular sieve when the room air enters the device, and allows the enriched oxygen to be collected. The device could provide approximately 90~96% of oxygen to patients on a continuous flow basis at a rate of 1L/min to 10L/min. The nasal cannula are not sold with the device, users need to purchase the accessories by themselves that are legally marketed. The products have not undergone biocompatibility assessment of condensate precipitates according to ISO18562-4, and it is not recommended to use humidification bottles. The maximum altitude the subject device can operate without degradation of concentration is 2000m.

I am sorry, but based on the provided text, I cannot extract the specific acceptance criteria and study details as requested. The document is a 510(k) summary for an Oxygen Concentrator, which primarily compares the subject device to a predicate device and outlines non-clinical tests performed. It does not contain sections detailing acceptance criteria for specific performance metrics with reported results, sample sizes for test sets, expert qualifications for ground truth establishment, adjudication methods, MRMC studies, standalone performance studies, types of ground truth used, or details about the training set.

The document states:

• "Clinical testing was not needed for this 510(k). The non-clinical performance testing described above is sufficient to support that the device can be used safely and effectively."

Therefore, there is no information about a study that would include elements like test set sample sizes, ground truth establishment, expert adjudication, or MRMC studies for this oxygen concentrator.

The "Performance Comparison" table in the document provides technical specifications and comparisons to the predicate device, but these are not presented as "acceptance criteria" with "reported device performance" in the format typically used for studies validating diagnostic or AI-based devices. The reported values are descriptive technical specifications rather than outcomes from a performance study against predefined acceptance criteria.

Therefore, I cannot provide the requested table and details because the provided text does not contain a study demonstrating device performance against explicitly defined acceptance criteria in the manner you described.

The JUMAO Oxygen Concentrator is intended to provide supplemental oxygen to patients with respiratory disorders, by separating nitrogen from room air, by way of a molecular sieve. It is not intended to sustain or support life.

JMC5A Ni oxygen concentrator is made up of mainframe and flowmeter. It is an electronically operated device that separates oxygen from ambient air. It provides high concentration of oxygen directly to patient/user through a nasal cannula or other methods.

The Jumao Oxygen Concentrator is a Pressure Swing Adsorption (PSA) type oxygen concentrator which takes 120V ~ power source as power source. The output of oxygen is 0.5 to 5 liter per minute. Room air enters the piston type compressor via a series of filters for removing dust particles. The output compressed air is directed by a pneumatic valve into one of the two sieve beds which is full of adsorption material - molecular sieve. Nitrogen is adsorbed by the molecular sieve as the pressure increases; oxygen flows through the molecular sieve and concentrates at the sieve bed bottom. The enriched oxygen is divided into two streams; one stream enters a storage tank. The pressurized oxygen is regulated down to the suitable pressure, an adjustable flow meter and out to the patient. At the same time the second bed is in exhausted status, the molecular sieve desorbs nitrogen as the pressure decreases; another oxygen stream from first bed enters the bottom of the second bed, promotes purging the nitrogen and is exhausted into the atmosphere. Two sieve beds exchange the role of oxygen concentration and continue to produce 93% oxygen to the patient.

This document is a 510(k) premarket notification for an Oxygen Concentrator (Model: JMC5A Ni) and primarily focuses on demonstrating substantial equivalence to a predicate device. It is not a study report designed to prove a device meets specific acceptance criteria through clinical or large-scale non-clinical performance studies with detailed statistical analysis.

Therefore, many of the requested details about acceptance criteria, study methodologies, sample sizes for test/training sets, expert involvement, and ground truth establishment are not present in this regulatory submission document as they would be in a dedicated performance study report.

The document states, "No clinical testing has been performed." and primarily relies on non-clinical (bench) testing and a usability study to support substantial equivalence. The "acceptance criteria" discussed are more akin to meeting specific established standards and performance specifications for an oxygen concentrator rather than criteria for an AI/algorithm-driven device's performance metrics (like sensitivity, specificity).

The Portable Oxygen Concentrator (Model: P2-E7, P2-E) is intended to provide supplemental oxygen in a home, institutional, or travel environment.

Portable Oxygen Concentrator (Model: P2-E7, P2-E) is a portable oxygen generator that is intended to release oxygen for respiratory by means of physical means (a molecular sieve). It supplies a pulsed high concentration of oxygen and is used with a nasal cannula to channel oxygen from the concentrator to the patient. The Portable Oxygen Concentrator is small, portable and may be used in home, institutional, or travel environment.

The portable oxygen concentrator consists of two parts: an oxygen concentrator and accessories. The oxygen concentrator is composed of compressor, battery, solenoid valve, molecular sieve, circuit control system, heat dissipation system, and a flow control device. Accessories include power adapters.

Model difference: The only different between model P2-E7 and P2-E is that P2-E7 has biggest output oxygen flow of 1.4L/min (at 7 gears) and P2-E has biggest output oxygen flow of 1.0L/min (at 5 gears).

The provided document is a 510(k) Summary for a Portable Oxygen Concentrator. It describes the device, its intended use, and a comparison to a predicate device to establish substantial equivalence for regulatory clearance. It does not present information about a study that assesses the device's performance against clinical acceptance criteria using human subjects or an AI algorithm.

Therefore, I cannot provide the requested information regarding:

• A table of acceptance criteria and reported device performance (in a clinical context).
• Sample size used for a test set or data provenance related to clinical performance.
• Number of experts or their qualifications for establishing ground truth for a clinical test set.
• Adjudication method for a clinical test set.
• MRMC comparative effectiveness study or related effect sizes.
• Standalone (algorithm only) performance.
• Type of ground truth used (expert consensus, pathology, outcomes data, etc.) for clinical evaluation.
• Sample size for a training set (as no AI algorithm requiring a training set is discussed).
• How ground truth for a training set was established.

The document focuses on non-clinical testing and engineering standards to demonstrate safety and effectiveness, and substantial equivalence to a predicate device, not clinical performance against acceptance criteria in a human study, nor does it involve an AI component.

The relevant information from the document related to testing and "acceptance" is as follows:

Acceptance Criteria (Implied by Standards and Comparison to Predicate):

While not explicitly stated as "acceptance criteria" in a clinical performance sense, the document demonstrates the device meets various safety, performance, and compatibility standards. The "reported device performance" in this context refers to the device's adherence to these standards and its characteristics in comparison to the predicate.

Study Proving Device Meets Criteria:

The "study" in this context refers to the non-clinical testing and validation performed to demonstrate substantial equivalence and adherence to recognized standards.

1. A table of acceptance criteria and the reported device performance: See table above.

2. Sample sized used for the test set and the data provenance: Not applicable in the context of human clinical data for this submission. The "test sets" refer to the specific units of the device models (P2-E7, P2-E) subjected to various engineering and functional tests. The data provenance is from Qingdao Kingon Medical Science and Technology Co., Ltd. (China) through bench testing. The document refers to "non-clinical tests performed." The testing is retrospective in the sense that the results were submitted for regulatory review after completion.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. Ground truth, in this context, is established by adherence to internationally recognized engineering and medical device standards (e.g., ISO, IEC, AAMI ANSI) and direct measurement of device characteristics. The expertise would lie in the engineers and testing personnel who conducted these standard tests.

4. Adjudication method: Not applicable. Standard technical testing and comparison against predicate.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done: No. This type of study is for evaluating human performance, often with or without AI assistance, in diagnostic tasks. This device is a portable oxygen concentrator, not an imaging or diagnostic AI device.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. The "software" in this device controls hardware functions (e.g., alarms, breath detection, display) and is deeply embedded, not a standalone AI algorithm for interpretation or diagnosis.

7. The type of ground truth used: For hardware performance, the ground truth is defined by the specifications in the relevant industry standards (e.g., oxygen concentration, pressure, noise levels) and the functional requirements of the device. For software, the "ground truth" is adherence to software development life cycle processes (IEC 62304) and correct execution of defined functions without critical errors.

8. The sample size for the training set: Not applicable. This device does not use an AI algorithm that requires a training set in the typical machine learning sense. The software is embedded control software.

9. How the ground truth for the training set was established: Not applicable. See point 8.
